The Role

We are seeking a DevOps Engineer to own and evolve our Jenkins Shared Library, powering multi-language builds across Java/Maven, Node/NPM, Python, Helm, Terraform, and containers. The successful candidate will deliver fast, secure, provenance-rich pipelines in line with SLSA standards, strengthen supply-chain integrity, and mentor teams on best practices.

Key Responsibilities

Design, maintain, and enhance Groovy pipeline steps for build, test, package, scan, and deployment processes.
Extend Python tooling for SLSA provenance, SBOM generation, hash/digest validation, and security scan aggregation (SonarQube, Sonatype IQ, SAST/Container).
Optimise pipeline performance using parallel builds, caching, scope-reduced BOMs, and dependency prefetching.
Ensure artifact integrity through correct SHA1/SHA256 mapping, reproducible builds, and evidence modelling.
Refactor and modernise legacy scripts, removing global state, consolidating hashing, and standardising templates.

Document CI/CD configuration standards, ci-config.yaml usage patterns, and pipeline conventions.

Mentor engineers on secure pipeline development and supply-chain security practices.

Troubleshoot, resolve, and prevent pipeline incidents and bottlenecks.

Essential Skills & Experience

7+ years of engineering experience, with at least 3 years in CI/CD platforms or DevSecOps.
Strong expertise in Jenkins Shared Libraries and Groovy scripting.
Advanced Python automation, including JSON/YAML processing and tooling scripts.
Deep understanding of Maven, NPM, and Python packaging; exposure to Helm, Terraform, and container image metadata.
Knowledge of supply-chain security, including SLSA, CycloneDX SBOMs, and digests.
Experience with SonarQube, Sonatype IQ, container and SAST scanning.
Proven skills in pipeline performance tuning, including caching, parallelisation, and dependency pruning.
Awareness of compliance and security standards relevant to CI/CD pipelines.

Desirable Skills

Experience with artifact signing and attestations (e.g., cosign, OCI).
Familiarity with Terraform module and Helm chart publishing patterns.
Experience in GitOps or release automation workflows.
Exposure to GCP or AWS cloud environments.
